If we a do a google search for the following string "Send free, anonymous and easy fake email", one of the sites we get is 'deadfake.com'...and many others. I can send an email to myself from myself by filling in the two fields at the website.Technically, what such sites seems to be doing is that, such mailers add an X-Mailer attribute to the message header indicating the message origin, and an X-Originating-Ip (a real one).How do I guard against such emails originating from fake email impersonations. Is there something I can do at our email gateway, proxy or exchange sever (2003) levels?
As an aside, what a great spam target collection tool. Nick -- Nick Owen WiKID Systems, Inc. 404.962.8983 http://www.wikidsystems.com Commercial/Open Source Two-Factor Authentication irc.freenode.net: #wikid
